I got an acan coral yesterday and I don't know where it will be happiest so I don't want to glue it down just yet. The problem is that the urchin won't let it stay in the same spot. I put it in yesterday and have had to move it back on the rock three times already so it hasn't had a chance to open. It is just one one big polyp for 25$, should I just bite the bullet and glue it down in a spot I think will work, flow wise and hope for the best?
